Description

Technical Field

[0001] This application relates to the field of elevator testing technology, and in particular to an elevator buffer testing device. Background Technology

[0002] Elevator buffers are safety devices for traction elevators. When the elevator car or counterweight bottoms out due to control failure, insufficient traction force, or brake failure, the buffer absorbs the kinetic energy of the car or counterweight to provide final protection to ensure the safety of personnel and the elevator structure. Therefore, it is necessary to conduct comprehensive testing on elevator buffers to ensure that their functions can be realized normally.

[0003] The prior art patent document with publication number CN214373240U provides an elevator buffer test device. This device uses an impact component and a counterweight component to quickly add counterweight blocks according to test requirements, saving the time consumed by counterweight loading and achieving high work efficiency.

[0004] Although the existing technical solutions mentioned above can achieve high work efficiency through the combination of impact components and counterweight components, they still have the following drawbacks: the existing technology requires manual cutting of the rope, which is dangerous and will indirectly reduce work efficiency.

[0005] In view of this, we propose an elevator buffer testing device. Utility Model Content

[0006] 1. Technical problems to be solved

[0007] The purpose of this application is to provide an elevator buffer testing device to solve the problems mentioned in the background art, which are inherently dangerous and indirectly reduce work efficiency, thereby achieving automatic rope cutting and increasing work efficiency.

[0008] 2. Technical Solution

[0009] An elevator buffer testing device includes a support frame;

[0010] A winch, on which a wire rope is connected and fixed;

[0011] A simulated car, which is slidably connected within a support frame;

[0012] The cutting mechanism includes a limiting frame fixedly connected to the simulated car. An insert frame is inserted into the limiting frame, and two insert posts are inserted into the insert frame. An abutment plate is fixedly connected to the end of each insert post. An abutment block is abutted between the two abutment plates. A motor is fixedly connected to the center of each abutment block. The motor is fixedly connected to the limiting frame. The abutment plates are slidably connected to the limiting frame. The end of the insert frame is fixedly connected to the other end of a steel wire rope.

[0013] By adopting the above technical solution and designing the cutting mechanism, the connection between the wire rope and the simulated car can be automatically cut off when the winch lifts the simulated car to an appropriate height. This allows the simulated car to safely fall onto the elevator buffer. Then, industrial high-speed cameras and other equipment can assist in detecting whether the elevator buffer meets the requirements. This not only ensures high safety but also guarantees work efficiency.

[0014] Preferably, a spring is fixedly connected to the end of the insertion post, and a limit cylinder is fixedly connected to the other end of the spring. The limit cylinder is slidably connected to the end of the insertion post and the abutment plate.

[0015] By adopting the above technical solution, during the cutting process, the motor output shaft drives the abutting block to rotate and abut the abutting plate. Then the abutting plate can drive the insertion post to slide out of the insertion frame. Subsequently, the insertion frame separates from the limiting frame, allowing the simulated car to fall freely. When reconnecting, the motor rotates again. Since the abutting plate is not driven by the abutting block, the spring design can drive the insertion post to reconnect with the insertion frame under the limit of the limiting cylinder. This allows the wire rope to be reconnected to the simulated car, making the connection more convenient.

[0016] Preferably, the abutment plate has a positioning groove in the middle, and the end of the abutment block is engaged with the positioning groove.

[0017] By adopting the above technical solution, the positioning groove can ensure the stable fit between the abutment plate and the abutment block with the help of the spring.

[0018] Preferably, the simulated car has multiple insertion slots inside, and counterweights are inserted into the insertion slots.

[0019] By adopting the above technical solution, the design of the plug slot and counterweight block can simulate elevators of different tonnages and adapt to the testing of elevator buffers of various specifications. Furthermore, the movable cooperation between the counterweight block and the plug slot can simulate the scenario of people inside the car, making the test results closer to reality.

[0020] Preferably, the lower part of the support frame is equipped with auxiliary detection mechanisms such as elevator buffers and industrial high-speed cameras.

[0021] 3. Beneficial effects

[0022] Compared to existing technologies, the advantages of this application are:

[0023] 1. This application, through the design of the cutting mechanism, can automatically cut off the connection between the wire rope and the simulated car when the winch lifts the simulated car to an appropriate height. This allows the simulated car to safely fall onto the elevator buffer. Then, industrial high-speed cameras and other equipment can assist in detecting whether the elevator buffer meets the requirements. This not only ensures high safety but also guarantees work efficiency.

[0024] 2. This application, through the design of the plug-in slot and the counterweight block, can simulate elevators of different tonnages and can adapt to the testing of elevator buffers of various specifications. Furthermore, the movable cooperation between the counterweight block and the plug-in slot can simulate the scenario of people inside the car, making the test results closer to reality.

[0029] The present application will be further described in detail below with reference to the accompanying drawings.

[0030] Reference Figure 1 and Figure 2 This application discloses an elevator buffer testing device. Support frame 1;

[0031] Winch 2, with a steel wire rope fixedly connected to winch 2;

[0032] Simulated car 3 is slidably connected to support frame 1;

[0033] The cutting mechanism 4 includes a limiting frame 5 that is fixedly connected to the simulated car 3. A plug frame 6 is inserted into the limiting frame 5. Two plug posts 7 are inserted into the plug frame 6. An abutment plate 8 is fixedly connected to the end of the plug post 7. An abutment block 9 is abutted inside the two abutment plates 8. A motor 10 is fixedly connected to the middle of the abutment block 9. The motor 10 is fixedly connected to the limiting frame 5. The abutment plate 8 is slidably connected to the limiting frame 5. The end of the plug frame 6 is fixedly connected to the other end of the wire rope.

[0034] The design of the cutting mechanism 4 can automatically cut off the connection between the wire rope and the simulated car 3 when the winch 2 lifts the simulated car 3 to an appropriate height. This allows the simulated car 3 to safely fall onto the elevator buffer. Then, industrial high-speed cameras and other equipment can assist in detecting whether the elevator buffer meets the requirements. This not only ensures high safety but also guarantees work efficiency.

[0035] Reference Figure 2 A spring 11 is fixedly connected to one end of the insertion post 7, and a limit cylinder 12 is fixedly connected to the other end of the spring 11. The limit cylinder 12 is slidably connected to the insertion post 7 and the end of the abutment plate 8.

[0036] During the cutting process, the output shaft of motor 10 drives the abutment block 9 to rotate and abut against the abutment plate 8. Then, the abutment plate 8 can drive the insertion post 7 to slide out from the insertion frame 6. Subsequently, the insertion frame 6 separates from the limiting frame 5, allowing the simulated car 3 to fall freely. When reconnecting, motor 10 rotates again. Since the abutment plate 8 is not driven by the abutment block 9, the design of spring 11 can drive the insertion post 7 to reconnect with the insertion frame 6 under the limitation of the limiting cylinder 12. This allows the wire rope to be reconnected to the simulated car 3, making the connection more convenient.

[0037] The abutment plate 8 has a positioning groove 13 in the middle, and the end of the abutment block 9 is engaged with the positioning groove 13.

[0038] The positioning groove 13 can ensure the stable engagement between the abutment plate 8 and the abutment block 9 with the help of the spring 11.

[0039] Reference Figure 3 The simulated car 3 has multiple insertion slots 14 inside, and counterweights 15 are inserted into the insertion slots 14.

[0040] The design of the plug slot 14 in conjunction with the counterweight 15 can simulate elevators of different tonnages and can adapt to the testing of elevator buffers of various specifications. Furthermore, the movement of the counterweight 15 and the plug slot 14 can simulate the scenario of people inside the simulated car 3, making the test results closer to reality.

[0041] The lower part of the support frame 1 is equipped with auxiliary testing mechanisms such as elevator buffers and industrial high-speed cameras.

[0042] The implementation principle of the elevator buffer testing device in this application embodiment is as follows: the winch 2 lifts the simulated car 3 to an appropriate height, the output shaft of the motor 10 drives the abutment block 9 to rotate and abut against the abutment plate 8, and then the abutment plate 8 can drive the insertion post 7 to slide out from the insertion frame 6. Subsequently, the insertion frame 6 separates from the limiting frame 5, so that the simulated car 3 can fall freely. When reconnecting, the motor 10 rotates again. Since the abutment plate 8 is not driven by the abutment block 9, the design of the spring 11 can drive the insertion post 7 to reconnect with the insertion frame 6 under the limitation of the limiting cylinder 12. In this way, the wire rope can be reconnected to the simulated car 3.

[0043] To test elevator buffers of different tonnages, a counterweight 15 can be added. The movable cooperation between the counterweight 15 and the insertion slot 14 can simulate the scenario of people inside the car 3, making the test results closer to reality.
